I suspect that you will get mostly negative responses from the members here. I wouldn't do it, but like many other members, I have an SUV driven by the wife that can handle it. It would definitely "violate" the sports performance purity of the six and be a questionable move. I suggest you find a beat up pickup truck for less than a grand, which would do the job much better. One practical question might be the pull out of the water on a wet ramp, depending on how steep - I know a jet ski doesn't weigh much, but with that torque, the tires break free rather easily.... (I do recall backing down a snow-covered hill that my six couldn't handle in the last snow event here in Buckhead...

Why would you want to get salt water all over your rear axle and suspension ??? very corrosive, and the sand, worse than having your swimming trunks full of it........lol
